FILM-WAXING MACHINE.

Application filed November 22, 1921. Serial No. 517,068.

To all 10/20 221 it may concern:

lie it known that I, MAURICE E. CLARK, a citizen of the l nited States, residing at Gre: nada, in the county of Grenada and State 0t Mississippi, have invented new and useful Improvements in Film-Waxing Machines, of which the following is a specificatlon.

My present invention has reference to a means for waxing motion picture films.

My object is to produce a means whereby a film ribbon will be drawn through a guide that has arranged therein rolls of wax positioned to exert a tension on the ribbon in its movement through the guide, to also support the ribbon in such movement and to apply to the marginal edges thereof a desired quan tity of wax.

A further object is to produce a waxing device for motion picture films comprising a guide which includes spaced parallel members connected to arrange the same only a slight distance away from each other greater than the width of the film ribbon, said side members having opposed openings to receive sticks of wax therethrough and to protect the same the proper distance to engage with the marginal edges of the ribbon when the same is drawn through the guide, said sticks being so arranged to cause an irregular travel of the ribbon through the guide and to also, by virtue of the contact of the opposed marginal edges with the sticks, to impart on the said edges a coating of wax.

The foregoing, and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this specification.

In the drawings Figure 1 is an end view of the improvement.

Figure 2 is a substantially central vertical longitudinal sectional view through the same.

Figure 3 is a top plan view.

As disclosed by the drawing, I make use of a guide which is in the nature of a channeled member, comprising a fiat base 2 having upstanding right angular parallel sides 1. The sides 1 are spaced away from each other only a slightly greater distance than the width of a ribbon of film 3 Which is to be drawn through the guide.

The sides 1 are provided with opposed round openings, the central openings being arranged a slight distance-above the end openings and through all of these openings 1 pass cross sectionally rounded sticks of wax or parafiin 4 respectively. Because of the particular and eculiar arrangement of the paraiiin'sticks in the guide, the film ribbon 3 will have its upper marginal edges in contact with the lower surface of the end sticks and will have its bottom marginal edges brought over and in contact with the central pair of paraffin sticks. The film ribbon 3, when drawn through the guide is tensioned by its contacting engagement with the sticks and because of this tension and its irregular travel through the guide will be brought into suflicient frictional engagement with the sticks as to remove therefrom a desired quantity of parafiin for waxing the edges of the film ribbon.

Having described the invention, I claim 1. In a film ribbon waxing means, a guide comprising parallel members spaced a distance from each other only slightly greater than the width of a film ribbon which is to be drawn through the guide, and waxing means for the marginal edges of the film projecting inwardly from the sides of the guide and irregularly spaced whereby, when the film is fed therebetween to cause the same to contact with the under faces of certain of the waxing means and the upper faces of the other waxing means to exert a tension on the film and to provide a support therefor when arranged in the guide.

2. In a waxing means for motion picture film ribbons, a guide comprising parallel side members, which are spaced from each other only a slightly greater distance than the width of the film to be drawn therebetween, said sides having opposed round openings arranged adjacent to its ends and at its center, the central openings being arranged slightly above the end openings, rounded paraflin sticks inserted through the openings ginal edges of the films will be in contavt from the outer sides of the guide with the end sticks and the lower marginal and projected through the openings edges of the said fihns will be in contact with 10 a distance to engage with the marginal edges the center sticks.

5 of the fihn ribbon, and the said film ribbon In testimony whereof, I afii-x my signabeing threaded between the projecting edges ture.
